CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 526,632, datedSeptember 25, 1894.

Application filed April 19, 1 8 94.

To all whom it may concern.-

Be it known that we, MINNIE MCPHAIL and FRANK KOPICKE, citizens of theUnited States of America, residing at Taunton, in the county of Lyon andState of Minnesota, have invented certain new and useful Improvements inOar-Couplings; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The object of this invention is to provide a car-coupling of the linkand pin type with a pin support which will be automatically re leasedand couple the cars when they come together; and it consists in animproved pin support which engages with a catch and is attached to thecar in such manner that when released from the catch it will fall bygravity and cause the pin to drop into the apertures therefor in thedraw head.

The invention further consists in the construction and combination ofthe parts, as will I be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of ourimproved coupling, showing the pin support elevated, and Fig. 2 is aside view showing two cars in position for coupling both having ourimproved coupling devices attached thereto.

A designates the drawhead which is attached to the truck-frame of thecar B in the usual manner to provide for a limited longitudinal movementof the same, the rear part of the draw-bar being encircled by a helicalspring to hold the drawhead normally projected.

The drawhead A is of the construction used a with the link and pincoupling, being pro- Serial No. 508,209. No model.)

a bar C which is bifurcated at its lower end to'embrace the draw-barrear of the drawhead and isprovided with a forwardly-projecting arm 0apertured to receive the coupling-pin, the upper end of the bar having acatch a and a slot 0 with which the crank portion 01 of a lever Dengages for elevating the pin support. The pin support is held inposition by a staple E which is driven into a block E attached to thefront end of the car, this connection permitting the said support tohave a vertical movement and the ends of the same a movement to and fromthe car, the block E acting as a fulcrum for this latter movement. Thecatch 0 of the pin support is adapted to engage a recess at the upperedge of the car, and when in engagement therewith the pin support isheld in an elevated position with the lower end of the coupling-pinwithin the upper aperture of the drawhead, in this position the partsbeing ready for coupling so that when the cars come .together therearward movement of the drawhead will throw the lower end of the pinsupport which will move the catch at the upper end of the same out ofengagement with the recess, the said pin support then falling by gravitycarrying with it the coupling-pin which passes through the link-chamberand into the lower aperture in the draw-head.

The crankshaft for elevating the pin support is journaled on top of thecar and is provided at its inner end with an arm d which engages theslotc in the pin support while its outer end is formed into a crank portionat from which extends a rod d to provide for rocking the shaft from theside of the car. It will be noted that as the crank-shaft is rocked toelevate the pin-support the inclination of the arm (1 will cause theupper end of said pin-support to ride upon the same and thus insure itsengagement with the recess at the edge of the car.

The device hereinbefore described provides for positively coupling thecars when they come together, and the construction and arrangement ofthe parts is such that they are not liable to get out of order.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. In a car coupling, the combination, of a pin supporting bar :0bifurcated at its lower end for engagement with the draw-bar rear of thedrawhead as shown and provided above the drawhead with an outwardlyprojecting" arm a apertured for the passage of the coupling-pin, the bar0' being connected to 'the car so as to be susceptible of a vertical androcking movement, a catch or projection c for engagement with the top ofthe car to hold the coupling-pin elevated when the drawhead isprojected, the parts being organized so that the coupling-pin isautomatically released when the drawhead is retracted, substantially;

as shown and for the purpose set forth.

2. In a car-coupling, the combination with a longitudinally movabledra-whead having apertures for the coupling-pin, of a'pin-support-consisting of a bar bifurcatedat itslower end to embracethe'draw-bar rear-ofthe head thereof and provided with an arm to whichthe coupling-pinislattached the npperendof the bar being s'o shaped thatit will-be-to-one side of the center of the car,'and provided adjacentto its upper end with a catch which is adapted to engage the car,thegpin-supl-port being attached to thecar to have "a vertical and anoscillating movement thereon, sub-.1

stantially as shown and for the purpose set forth.

3. in an automatic coupling device for cars, the combination with adrawhead, a pin supporting bar 0' which is bifurcated at its lower endfor engagement with the draw-bar rear of the'drawhe'ad, said barcarrying the coupling-pin, a staple or guide E carried by the car bodythrough which the bar 0' passes so that the same can have a sliding androcking movement, a catch 0' for engagement with the car body, and acrank-shaft D one member of which passes through the bar 0 and
